Janitza Prodata 2 5224001 Data Sheet

40

The ProData 2 can be set as a Modbus gateway with 
the following limitations:

•  In this mode, the ProData 2 cannot be used as a 

Modbus RTU slave device.

•  In this mode, the ProData 2 converts Modbus TCP 

packages from port 502 (only TCP) to Modbus 
RTU and sends these via the RS485 interface.  
If a response is received via the RS485 interface 
within a timeout period that can be set, this is 
converted to Modbus TCP again and sent via 
the IP connection.

•  The ProData 2 can only forward queries (e.g. 

from the GridVis software) to a Modbus slave 
device. It 

CANNOT query Modbus slave devices 

independently.
